VAPOR-LAM P.

SPECIFICATION forming part of Letters Patent No. 561,967, dated June 16, 1896.

Application filed December 14, 1895. Serial No. 572,141. (No model.

To all whom it may concern.-

Be it known that 1, ROBERT CORSCADEN, a citizen of the United States, residing at Providence, in the count-y of Providence and State of Rhode Island, have invented certain new and useful Improvements in Vapor-Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters of reference marked thereon.

The present invention has relation to that class of lamps or other similar devices for the production of artificial light through the vaporization of a liquid; and it consists in a lamp or other similar illuminating device constructed substantially as shown in the drawing and hereinafter described and claimed.

In the accompanying drawing, Which represents a sectional elevation of my invention, A designates the body of the lamp or other illuminating device, which may be of glass or metal, as found most desirable, and has a neck a, said body containing the liquid to be vaporized, such as acetylene fluid, which is retained therein and not permitted to form into a gas or vapor as an illuminant until desired for use.

An interior-screw-threaded collar B is fitted over and around the neck a and secured thereon in any suitable and well-known manner, and engaging with the screw-threaded end of the collar is the screw-threaded end of a tubular coupling 0. This coupling is screw-threaded at each of its ends, so as to form a connection between the body A and the tapering tube D, said tube at its lower end having an interior-screw-threaded flange b, with which engages the screw-threaded end of the tubular coupling 0. The tubular coupling is provided .with a suitable faucet E, of any well-known and desirable construction, which faucet controls the opening in the tubular coupling and the supply of gas or vapor to the burner or shuts the supply off altogether.

The supply-tube D, through which the gas.

with a support F for a glass chimney G, the

tube being of such length as to extend some distance above the support and lower end of the chimney. The tapering supply-tube D terminates at its upper end in a tubular eX- tension 0, having a supporting-shoulder cl at its base, upon which rests the sleeve 6 of a conical burner H. This burner has openings f to admit air for promoting combustion, and has a concavo-convex cap I, which is perforated for the passage of the gas or vapor from the burner.

The top of the burner H has a circumferential rim g, which is perforated to admit of ventilation.

In place of perforated sheet metal wiregauze may be used wherever it may be found of benefit, the same result being attained in either instance, and any such changes in the details of construction as would come with in ordinary mechanical skill may ,be made without departing from the principle of my invention.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

A lamp consisting of a body, a tube or pipe extending therefrom, a cook or faucet to control the flow of vapor, and a support F, on the pipe for the chimney, combined with a burner on the upper end of the pipe, and a means extending from the burner to hold the chimney in position, said means allowing air to pass freely through,substantially as shown.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

ROBERT OORSOADEN.
